铝棒在进入挤出机前进行预热。传统观念,也许㊣酒吧必须在炉内加热固溶温度、铝卷但经验表明,现在还不确定。只要铝棒浇铸正确、均匀化，无需在预热炉中达到固溶温度。
　　The aluminum bar is preheated before entering the extruder. Traditionally, bars may have to heat solution temperature and aluminum coil in the furnace, but experience shows that it is still uncertain. As long as the aluminum bar is cast correctly and evenly, it is not necessary to reach the solution temperature in the preheating furnace.
　　铝棒在进入挤出机前进行预热。传统的想法,也许,炉内的酒吧必须加热到固溶温度、Ⅻ但经验表明,现在还不确定。只要适当的浇铸和均匀化，就不需要在预热炉中达到固溶温度。铝棒炉的唯一用途是软化金属，而不是在现代的铝挤压厂生产。如果金属加热对铝盘管的销售不够，铝盘管的销售计算公式不能顺利通过模具。如果要有效地释放铝棒时，加热，挤出速度必须非常低。

　　The aluminum bar is preheated before entering the extruder. The traditional idea, maybe, is that the bar in the furnace must be heated to the solution temperature, ? but experience shows that it is still uncertain. As long as the proper casting and homogenization, it is not necessary to reach the solution temperature in the preheating furnace. The only purpose of the aluminium bar furnace is to soften the metal, not to be produced in modern aluminium extrusion plants. If the sales of aluminum coil by metal heating is not enough, the sales calculation formula of aluminum coil can not pass the mold smoothly. If the aluminum bar is to be released effectively, the extrusion speed must be very low.
　　铝棒预热区温度测量的典型问题有:
　　Typical problems of temperature measurement in preheating zone of aluminum bar are as follows:
　　1. 两点热电偶读数将较低
　　1. Two point thermocouple reading will be low
　　2. 两点热电偶的日常维护经常被忽略
　　2. Routine maintenance of two-point thermocouple is often ignored
　　3.均匀化热处理温度是铝棒的关键参数
　　3. Homogenization heat treatment temperature is the key parameter of aluminum bar

　　4. 操作员容易使铝棒过热
　　4. The operator is easy to overheat the aluminum bar
　　5. 操作者倾向于降低挤压速度来微调铝棒在挤压过程中的温度变化
　　5. The operator tends to reduce the extrusion speed to fine tune the temperature change of aluminum bar during extrusion
　　6. 过度加热和缓慢挤压浪费预热能量
　　6. Excessive heating and slow extrusion waste preheating energy
　　棒材应加热到可挤压的更低温度。线圈销售规格还必须确保挤出机出口温度达到目标值。通过降低铝棒的预热温度，可以提高挤压速度，铝盘管的销售价格可以降低加热炉的能耗。实践证明，这种经济数据的改变，可以节省燃气加热炉15-20%的能源消耗。
　　The bar shall be heated to the minimum temperature at which it can be extruded. The coil sales specification must also ensure that the extruder outlet temperature reaches the target value. By reducing the preheating temperature of the aluminum bar, the extrusion speed can be increased, and the sales price of the aluminum coil can reduce the energy consumption of the heating furnace. The practice shows that the change of economic data can save 15-20% energy consumption of gas heating furnace.
　　针对燃气加热炉进口廉价产品，采用两点热电偶测量铝棒的温度范围。因为这种仪器维护要求高,Ⅴ使用这种仪器本身的优点,还是非常昂贵的维护铝卷销售、铝卷销售测试报告或失去准确性。一些铝型材厂已经开始使用非接触式传感器来检测和控制铝型材加热段的温度。不仅减少了依赖联系热电偶温度计,⒇,减少了维护问题由于仪器本身的局限性和准确性。
　　Aiming at the imported cheap products of gas heating furnace, the temperature range of aluminum bar is measured by two-point thermocouple. Because of the high maintenance requirements of this instrument, v. the advantages of using this instrument itself, or very expensive maintenance aluminum sales, aluminum sales test report or loss of accuracy. Some aluminum profile factories have begun to use non-contact sensors to detect and control the temperature of the heating section of aluminum profile. It not only reduces the dependence on contact thermocouple thermometers, but also reduces the maintenance problems due to the limitations and accuracy of the instrument itself.
　　在感应加热炉系统中，红外温度传感器直接对准铝棒的表面来引导力，第七个可以直接了解温度“产生和推进”，而第四个可以减少两点热电偶使用的不一致性。同样,为燃气热水器,传感器可以安装在炉出口(挤压管入口)理解铝棒的表面温度,Ⅱ也用于正确的炉内的温度热电偶或红外测温仪温度偏差。铝棒温度测量部分酒吧是更理想的位置,Ⅵ检查均热段温度。侧部的温度也要测量，因为这一侧会先接触模具。
　　In the induction heating furnace system, the infrared temperature sensor directly aims at the surface of the aluminum bar to guide the force, the seventh can directly understand the temperature "generation and propulsion", and the fourth can reduce the inconsistency of the use of two-point thermocouples. Similarly, for the gas water heater, the sensor can be installed at the furnace outlet (extrusion pipe inlet) to understand the surface temperature of the aluminum bar. II is also used for the correct temperature thermocouple or infrared thermometer temperature deviation in the furnace. Aluminum bar temperature measurement part of the bar is the most ideal location, Ⅵ check the soaking temperature. The temperature of the side should also be measured, because this side will contact the mold first.
　　对于梯度加热的铝条，可以在铝条输送带一侧安装一个传感器来了解铝卷销售的温度，也可以安装两个传感器来测量铝条两端的温度。准确的梯度加热温度对连续输送铝棒到挤出机是非常重要的。不准确的温度测量会使梯度加热失去意义。
　　For the gradient heating aluminum strip, a sensor can be installed on one side of the aluminum strip conveyor belt to understand the sales temperature of the aluminum roll, or two sensors can be installed to measure the temperature at both ends of the aluminum strip. Accurate gradient heating temperature is very important for the continuous transportation of aluminum bars to the extruder. Inaccurate temperature measurement will make gradient heating meaningless.
